The c.262T>A (p.S88T) alteration is located in exon 1 (coding exon 1) of the ISG20L2 gene. This alteration results from a T to A substitution at nucleotide position 262, causing the serine (S) at amino acid position 88 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
